I am working on a project that i hope to use these ball sensors in. my problem is there is very little application information that can be found on the items.
i am able to apply the 12v to the sensor and read back the output as 6.5v no ball and 10.8 with a ball present changing the external resistor has little change to the over all voltage so i can not directly feed that into an Arduino or esp32

normally one would use a voltage divider to get the voltage into range but that does not work in this case as you can see in the part schematic that that is how they get the voltage as the output

I have tried the screen clips of the video but had no luck with that as well. i was also thinking that an optocoupler would work but i can not seem to make that do it as well

so the primary goal is to translate that 6.5 to 10.8 to a logic level of 0v to 5v or 0v to 3.3v or a high / low signal for the micro to process

I was thinking that these parts are used in the machines already and their primary use is for pachinko ball detection, that there must be a schematic of a machine that uses these 2 wire items and the surround circuit might glean the interface method used in the machines.

or for that mater maybe some one has already figured out the interface for the sense or SBC and could share.
